At the 20% cumulative failure rate,
SN100C is 1.8 times more resistant to vibration than Sn-3.9Ag-0.6Cu (SAC)
with Sn finished leads and 1.6 times more than SAC with NiPdAu lead finish.

Charpy Impact Test Results

SN100C Excellent Resistance to Impact at Temperatures as low as -120℃!

SN100C lead-free solder proved to be superior to Sn-37Pb and silver containing lead-free solders by retaining its fracture toughness to a temperature as low as -120℃ in the Charpy Impact Test.

The Charpy Impact Test was performed with the temperature range of -195℃ to 100℃ on lead-free solders, Sn-5%Ag, Sn-4%Ag-0.5%Cu, Sn-3%Ag-0.5%Cu, Sn-0.7%Cu(Ni) known as SN100C, 99.99%Sn, and Sｎ-0.7%Cu as well as Sn-37Pb.  It was found that Sn-0.7%Cu(Ni) (SN100C) resulted in superior impact resistance at low temperature, as low as -120℃, in comparison to Ag containing solders and Sn-37Pb.
